PROBLEM TO BE SOLVED: To provide a crushing method of coal for a coke oven, which, upon crushing the coal by an impact type crusher without using a sieving device, inhibits generation of less than 0.3 mm coal resulting from the crushing. SOLUTION: In the crushing method of the coal for the coke oven by the impact type crusher, the method inhibits generation of less than 0.3 mm coal resulting from the crushing, by regulating a peripheral speed of a rotor 5, or the peripheral speed of the rotor and a gap (W1 and W2) between a rotating edge (a hammer 4) and a fixed blade (a milling plate 6), on the basis of crushing characteristics of a crushability index or a carbonization degree index of the coal.
